About ADAS

The Atomic Data and Analysis Structure (ADAS) is an interconnected set of computer codes and data
collections for modelling the radiating properties of ions and atoms in plasmas. It can address plasmas ranging
from the interstellar medium through the solar atmosphere and laboratory thermonuclear fusion devices to technological
plasmas. ADAS assists in the analysis and interpretation of spectral emission and supports detailed plasma models.

There are four main components of ADAS:

A graphical interactive system which allows immediate calculation and display of the derived quantities, such as effective recombination coefficients and
photon emissivity coefficients, which are used in practice to interpret plasmas. It includes pedagogical tools for exploring coefficient behaviour as a
function of plasma parameters and an ability to create tabulations of relevant data.

A very large database of fundamental and derived atomic data.

ADAS includes extensive subroutine libraries. These include utilities which range from basic atomic calculations such as Gaunt factor generation to
ionisation equilibria evaluation. They also include a key range of routines for accessing the database and delivering data to user codes. FORTRAN, C, C++, IDL and
MATLAB are supported.
